The rules are changing around what you need to travel to Europe, including to some of the cheapest countries to visit, with a moving target on a planned update. This year, however, you won't have to do anything different.
Starting in "the first half of 2025," Americans will need one additional approval to enter countries in the European Union. To visit, you'll have to apply for approval under the European Travel Information and Authorization System (ETIAS). You will apply online, and the authorization, which will be linked to your passport, will account for short-term stays, including up to 90 days in a 180-day period.
